Question
Thank you in advance for your help. I know nothing about coins  but found what i think is a repunched mintmark on the kennedy 1968d. This coin is in good condition considering the age.
The D underneath is visible with the naked eye on the entire curve of the D. Would this have any value above 50 cents? And if so, would it be best to send in for grading? sorry- no pics.

Answer
Hello Mike,                                   

This is an error worth looking at. If it is Mechanical doubling it has not added value but if it is another type or if the D punch moved and was struck again it carries a higher premium as much as $50 has been paid but around $5 to $10 is more common. The value rule is the greater the error the greater the price.
Error coin collecting is a specialty branch outside of coins collecting. There is no fixed pricing on these error coins published and each coin would have to be seen to be evaluated.

To find out what yours may be worth it would have to be seen to be accurately appraised. A photograph would not really help with this. If you write back with the general location (nearest large cities) and telephone area code or codes and some zip codes in your area, I can direct you to an AMERICAN NUMISMATIC ASSOCIATION MEMBER/DEALER near there. They are ethical and trustworthy. I hope this information Helps.

RPM is an abbreviation for re punched mint mark. With a quick search I found no listing for an rpm on the 1968 half.

This does not mean you do not have one just that there is no listing for one.

You can try CONECA at   http://conecaonline.org the club is the best in identifying new and rediscovered die errors. You can also try email conecawebsite@koinpro.com

If it is only a machine doubling it has no added value associated with it on any coin. And I often see this still happening with the modern equipment the mint now has.

The edge of each letter is fully doubled as is the “serif” (the point where the letter style juts out slightly at the points of the letters form).

It first may look like machine doubling that is a flat shelf-like shape on the letters but machine doubling would not show doubling on the serif part.

Here is a good web page The National Collectors Association of Die Doubling describing the difference between hub doubling and machine doubling:

I hope this information Helps.
